Canada's commitment to net-zero will certainly include all greenhouse gases. But it will also be limited geographically to the emissions generated in Canada, in all sectors, not only in oil and gas.
We must remember that this conforms to international standards of measuring GHGs, requiring each country to account for the emissions produced within its borders. Emissions from exports that produce GHGs are accounted for in the country that uses them. I don't know whether that answers your question.
